The given question is incomplete as the options are not provided. The correct options for this questions are as follows-
(1) Good heat conductivity
(2) Good electrical conductivity
(3) Low melting point
(4) High melting point
Thus, the question now is solved below as:
Answer:
Option (3)
Explanation:
Molecular substances are simply defined as those substances that are comprised of more than two atoms and are interlinked with one another. These atoms are linked with each other by the weaker intermolecular forces. This weak bond reflects the low and high melting point of the substance.
These molecular substances differ from the molecular compounds because, in the case of molecular compounds, the atoms are linked with one another by a strong covalent bond.
Thus, the correct answer is option (3).
Answer:
3, 5, and 6, that should be the answer
Answer:
Explanation:
Carton cycle consists of four thermodynamic processes . The first is isothermal expansion at higher temperature , then adiabatic expansion which lowers the temperature of gas . The third process is isothermal compression at lower temperature and the last process is adiabatic compression which increases the temperature of the gas to its original temperature .
So the given process of isothermal compression must have been done at the temperature of 300K , keeping the temperature constant .
Work done on gas at isothermal compression is equal to heat transfer .
work done on gas = 80 x 10³ J
work done on gas = n RT ln v₁ / v₂
n is number of moles v₁ and v₂ are initial and final volume
molecular weight of gas = 28.97 g
1.5 kg = 1500 / 28.97 moles
= 51.77 moles
work done on gas = n RT ln v₁ / v₂
Putting the values in the equation above
80 x 10³ = 51.78 x 8.31 x 300 x ln v₁ / .2
ln v₁ / .2 = .62
v₁ / .2 = 1.8589
v₁ = 0.37 m³
Answer:
2kg
Explanation:
100N = Force 50m/s²= Acceleration
Mass=?
the equation is;
Mass(kg)= Force(N) ÷ Acceleration (m/s²)
100÷50=2
